To all l107mm it 'may 00a/fern,

Be it known that l, Evnnn'rr L, SHAIN, a citizen of the United States, residing at Crown Hill, in the county of Kanawha and State of lVest lrirginia, have invented new and useful Improvements in Rail-Bonds, of which the following is a specification.

The present invention relates to an electric bond for railway rails, and the primary object of the invention is to produce an article of this character which shall.' be securely connected with the rails and sustained thereon by a conductor or bond member whereby an electric connection between the rails is assured.

vlilith the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following speciiication and falling Within the scope of the appended claims.

ln the drawing: Figure 1 is a perspective view showing two rails bonded in accord ance with the present invention, Fig. 2 is a detail sectional view taken through one of the clamping members and its securing bolt,'

Fig. 3 is a detail perspective View of one of the clamps, and 4 is a reduced sectional view on the line 4-4 of Fig. 3.

Referring now to the drawing in detail, R-R designates the meeting ends of tivo railway rails of the ordinary construction.

Arranged upon Athe base iiange ci each of the rails is a clamp iv. Each of the clamps comprises a horizontally straight base 3 having'y an enlarged outer end ,or head 4 whichjs integrally formed with an inwardly angularly extending jaw 5. The'angular extension 5. with relation to thestraight base 3 permits of the clamps being forced into tight engagement one with each oi' the The head 4 of each of the clamps is provided with a longitudinally arranged opening 6y and the base 3 has its underface formed with a channel in a line with -said opening as indicated by the numeral 7 ,Y

' The numerals 9 designate hook members which are formed vwith longitudinally eX- tending threaded Shanks 8., the said hooks each engaging with the 'longitudinal flanges 'of the rails opposite that engaged by the clamps,lwhile their Shanks 8 are arranged within the channels 'i' and have their threaded ends'passed .through the openings 6 of thesaid clamps. The heads 4 have their outer faces, above the opening 6' provided With transversely arranged grooves 14, the inner walls of the said grooves being rounded and providing seats for a longitudinally extending straight bond wire 15. The Wire is preferably of a greater Width than the depth of the groove 14 and -so slightly projects beyond the grooves and beyond the straight faces of the heads 4.

The numerals 15 designate Washers which are passed over the extending ends of the shanks 8 oi' the hooks 9 while the said Shanks also receive the coiled ends 10 provided upon a curved clamp connecting member 11.

12 designates bolts which are screwed against the eyes 10 of the connecting member 11 which force the coiled or rounded ends 10 of the member 11 tightly against the `washer and consequently the Washer tightly against the bond 15.

By constructing the connecting member 11 of a curved wire it will be noted that the clamps will not be influenced by a movement of the rails at the meeting ends thereof, and further the conductor 15 is of a sufficient length'to give in ailongitudinal direction without becoming disconnected from the clamps or losing its efiiciency. The clamps are, of course, constructed of some electric said washer 16. The construction is such that the spacing member 1'1 will retain the clamps in proper relation with each other against danger of sliding longitudinally of the rails. to be removed from the grooves 14 Without entirely separating the nuts 12 from the threaded Shanks 8 oi-I the hook members, and the washer membersl being fiat and round in plan may be permitted to rotate or re.

volve upon the shanks of the hooks Without permitting the conductor member 15 leaving theseats 14 and also the said Washersbeing sof asl

The conductor 15 may be applied comparatively thin will be readily com-r/ pressed against the member 15.

From the above description, taken in co/nf l nection with the accompanying drawing, th

' simplicity of the device as well 'as the advan' tages thereof will, it'is thought, be .perfectly apparent to those skilled in the art to which such invention appertains Without further -detailed description.

Having thus described the invention,-What I claim is:

1. The combination with alining rails and clamp members having bolts securing the same to the edges of the flanges of the rails, and said clamps having their outer faces provided' with grooves, of a flexible bond member received in the grooves and projecting therethrough,v a washer upon each of thebolts contacting with the said bond, and

nuts threaded on the bolts engaging with the `washers to force the same against the bond `to compress the latter 'in the grooves.

2. The combination With two connected railsclamps arranged on theV edges of the ange's of the rails and bolts securing the clainps'to the said rails, the said clamps having registering depressions which are of a depth greater than a half circle, a flexible bond wire arranged in the groovesand projecting therethrough, a washer upon each of the bolts contacting with the bond, a wire spacing member having its ends foi-ined with eyes 'which are received in the bolts and nuts threaded upon the bolts contacting with the said eyes to force the saine into engagement with the washers to cause the latter to press the bond against the walls of the grooves.

In testimony whereof l affix my signature in presence of two witnesses.
